the differences you're seeing are exactly why bold font files exist, because they correspond to stylish variations of the font shapes, not plain emboldening.

I'm closing this bug because I don't think we can easily come up with an algorithm that does what you ask (especially one that works with all kinds of fonts)

I'm not sure whether this really is possible without detailed
analysis of the outlines. Let's see what David thinks to whom
I've assigned this bug report.

The serif fonts usually has varied line width. where some line is slim and some is thick say. and the original bold font is following that rule. but it looks weakness on the emboldening. it may be improvement on the embolden algorithm.
I attached the image of comparing between the synthetic embolden'd glyphs of the serif font and the glyphs from the real Bold serif font.
